Abstract
Abstract A cyclohexane derivative having a low viscosity, a broad nematic phase temperature range, a good compatibility with other liquid crystal components even at low temperatures and a large positive dielectric anisotropy value, and a liquid crystal composition containing the cyclohexane derivative are provided, which cyclohexane derivative is expressed by the formula wherein R represents an alkyl group of 1 - 10 C and A represents a hydrogen atom, a halogen atom of F, Cℓ or Br or a cyano group.
